It is the 29th in the world selected on the list of top gold producer that it relatively little size and this is the important considering New Zealand country produces Approximately 10.6 tonnes of gold per year and has much undeveloped gold resources.
Gold has won the top mineral resource in New Zealand and make a significant contribution to the economy of the country also. The mining sector employees more than twenty thousand people, and Approximately 1% of GDP to contribute of in the country.
In the mining industry the flotation cell used to separate the valuable mineral ore from mineral impurities, and based on differences from surface properties of the minerals substance to be separated in the flotation cell equipment, where in hydrophilic substances remain in the water phase, whereas the hydrophobic substance will be tied to the air bubbles and will be brought to the surface the solution and form a froth, so that it can be separated from the liquid. In a simple flotation equipment used for the separation of one or more mineral, with other minerals by flotation or commonly referred to as flotation technique, flotation machine is a useful basic equipment for mineral ore separation process from non-ferrous ores and other minerals.
Shaking table for gold separation process is the equipment used in the processing of mineral ores to separate the gold metallic minerals with other impurities. Gold dust separation process with shaking table equipment through gravity separation concentration method is in principle based on the difference of the physical properties of a mineral density. The means used in the process of separating gold of impurities by shaking table equipment utilizing media thin stream of water at the surface of the shaking table. Concentration or separation method utilizing gravity difference in the density of gold (19.3 tonnes / m3) with a density other types of minerals in the rocks (which generally range from 2.8 tonnes / m3). Because the gold mineralize material has mineral impurities or mineral carrier.
The process of separating gold with spiral concentrator is the process of separating gold using equipment by utilizing gravity system for obtaining gold ore. Spiral concentrator is one of the most effective ways and low cost in the mining industry which is used in the separation of mineral ore. One of the benefits of a spiral concentrator devices have no moving parts. The separation process mineral ore concentrates in gold mining in general should be done gradually, and a function of the mineral separation process to separate gold ore from dirt mineral or bearer minerals
Gold smelting process is the most important in the final stages of processing the gold. In the gold mining industry the smelting process used to make a Dor Bar and purification process that utilizes heat with a temperature high pressure. In general, the most basic definition of a gold smelting is the final stage of the process of refining gold from gold processing.
Before stage gold smelting process, The mining industry carry out a gold mineral mining activities from the earth, where the mining process through several stages of processing. The process of extracting and gold mineral search is an initial stage of mining. Then proceed to the processing of minerals from the mining area to the into mineral processing systems. Some ways of processing the gold minerals in the mining industry before the final stage gold smelting process, such as the processing of gold by Heap leaching methods, flotation process which produces mineral ore concentrate, tank leaching process is the processing of gold by washing or the process of dissulotion gold from mineral rock in the tank which would later produce a mineral concentrate gold ore.
Sabodala gold mine is a large-scale gold mining in the region of Senegal.

Sabodala gold mine in Senegal is owned and operated by Sabodala Gold Operations (SGO) which is a subsidiary of Teranga Gold Corporation based in Toronto, Canada with a ownership of 90% and the remaining 10% owned by the Government of the Republic of Senegal.
Gold processing techniques using activated carbon or Gold leaching process with Carbon In Pulp in gold mining is a way to separate the gold metal or extraction of separation of minerals gold with other impurities. Where part of the processing of Carbon In Pulp using cyanide solution to separation. The processing of gold first time with using a Carbon In Pulp (CIP) introduced in gold mining in the early 1980s, and is considered as a process that is simple and cheap in the gold mining industry. But processing using cyanide in gold mining if not done correctly, would harm the surrounding environment.
For separation gold process by means of Carbon In Pulp needed an activated carbon which serves as metal absorbent material and activated carbon material mostly made from coconut shells. In addition to from that required cyanide to stage gold mineral dissolution process of the sludge. Before the leaching process in Carbon In pulp, mineral rock must have a size that such as flour, which later on will used as a slurry.
Gold mining in Saudi Arabia in decades are now able to put the production of gold mining in the world market, although Saudi Arabia is the largest oil producer in the world, but in around 1997 the government of Saudi Arabia established the Saudi Arabian Mining Company (Ma'aden) which is an investment in the mining sector. The Saudi Arabian government involving several youths and the surrounding community deployed in mining exploration.

Copper came from most of the continents in the world. As in all mining operations, the ore must usually be beneficiated (concentrated). To get the copper content of the ore, then need a copper extraction process which consists of a series of chemical processes, physical, and a process by means of electrochemical. The extraction process can be done by froth flotation process of copper ore, because it is considered a very practical way in the copper mining industry
Froth flotation process is considered the most widely used method for ore beneficiation. In copper ore flotation is a precious mineral separation process from of ingredients worthless or other valuable minerals by a induce process the mineral ore, so that ore minerals can accumulate and be on the surface of the foam.
Video of the copper flotation process in this below is a separation process the copper minerals at the mill using froth flotation.

Underground mining process is done when the mineral stone, or precious metals found in very long distances to be at a depth of soil. Underground mining techniques used to excavate hard minerals, mainly those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds. And The processing of underground gold mines is used where the depth of mineral ore below the surface makes open-cut mining uneconomic
Gold prospecting in beach is an accumulation of valuable minerals formed by gravity separation during sedimentary processes and in geology called placer deposits . Beach placers form on seashores where wave action and shore currents shift materials, the lighter more rapidly than the heavier, thus concentrating gold .
Placer environments typically contain black sand, a conspicuous shiny black mixture of iron oxides, mostly magnetite with variable amounts of ilmenite and hematite. Valuable mineral components often occurring with black sands are monazite, rutile, zircon, chromite, wolframite, and cassiterite.
Among the examples of beach placers are the gold deposits of Nome, Alaska; the zircon sands of Brazil and Australia; the black sands (magnetite) of Oregon and California; and the diamond-bearing marine gravels of Namaqualand, South Africa.
Copper extraction techniques refers to the methods for obtaining copper from its ores. The method used to extract Copper Ore depends on the nature of the mineral ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores.
Coppercan be extracted from non-sulfide ores by a different process . Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper sulfate solution.

How to process gold ore in the mining ? This is the Video How To Process Gold Ore In Nevada Gold Mines
Gold
mining is the gold mining process or gold ores from the ground. There
are several techniques and process of gold which may be extracted from
the underground. Gold mining in Nevada, a state of the United States, is
a major industry, and one of the largest sources of gold in the world
Until
recently, gold exploration and gold mining production in Nevada has
been focused on low grade surface deposits mined as open pits. As they
probed deeper, they discovered even richer gold deposits. Development of
these higher grade gold deposits as underground mines and the
probability of discovering similar high grade deposits below Nevada's
scarcely explored vast overburden has added new excitement to the
state's gold potential.
Gold
Mining in Nevada has a vast assortment of rocks and minerals. Igneous
rocks include those from gabbro, diorite, and granite intrusions, and
basalt, andesite, and rhyolite flows, breccias, and tuffs. Sedimentary
rocks include conglomerate, sandstone, siltstone, shale, argillite,
limestone, and dolomite. Metamorphic rocks include gneiss, schist,
phyllite, slate, marble, hornfels, and skarn and various other types of
metaigneous and metasedimentary rocks. Many types of minerals, both
common and obscure, are also present.
